I hate cheap toy type RTRs but on the other end of the spectrum you have ARTRs like this:
I can understand why builders with skills like Bryan wonder at people like me spending so much money on something I can not even claim to have build myself- what have I learned?
I have considered a fleetscale hull but I really don't have the confidence to build a scratchbuilt superstructure let alone producing a deck with planking details

Brought a robbe U47 and it was a disaster, spent so much money and had a load of ruined plastic parts to show for it (just how the heck to you cut out some of those parts in that tuff plastic)- actually ended up stabbing myself in the hands a couple of times with a Stanley knife. I did build a Model slipway coaster took me about 7 months but had a difficult time with the painting. I used car sprays and was happy with the result until 6 months later when the painted seemed to start splitting and crazing in parts. Actually brought another coaster kit as I love the subject and get this- I sawed it in half and have successfully lenghend the hull! Thing is I keep thinking of the mess I'm going to make painting it so I've done no work on it since August last year.
I have learned that building a kit is a very expensive business with no promise that I can pull it off- for me it's a gamble. On the other hand I can buy stuff like the ARTRs on the Graupner site for the same amount of money I spent on just building/painting a large kit.
So with my past experiences what makes more sense to you?
Besides I've added details on the the Prinz and rebuilt parts like the catapault from scratch. Then there was the question of wiring up 3 motors and all the rest of the electronics so some skills are still needed.
